Giant Planet Occurrence in the Stellar Mass-Metallicity Plane [PDF]

open access: yes, 2010
Correlations between stellar properties and the occurrence rate of exoplanets can be used to inform the target selection of future planet search efforts and provide valuable clues about the planet formation process.

Origins of Eccentric Extrasolar Planets: Testing the Planet‐Planet Scattering Model [PDF]

open access: yesThe Astrophysical Journal, 2008
(Abridged) In planetary systems with two or more giant planets, dynamical instabilities can lead to collisions or ejections through strong planet--planet scattering. Previous studies for simple initial configurations with two equal-mass planets revealed some discrepancies between the results of numerical simulations and the observed orbital elements of

The Astrobiology of Alien Worlds: Known and Unknown Forms of Life

open access: yesUniverse, 2020
Most definitions of life assume that, at a minimum, life is a physical form of matter distinct from its environment at a lower state of entropy than its surroundings, using energy from the environment for internal maintenance and activity, and capable of

Chaotic zone boundary for low free eccentricity particles near an eccentric planet

open access: yes, 2006
We consider particles with low free or proper eccentricity that are orbiting near planets on eccentric orbits. Via collisionless particle integration we numerically find the location of the boundary of the chaotic zone in the planet's corotation region ...

Combining LiDAR and Spaceborne Multispectral Data for Mapping Successional Forest Stages in Subtropical Forests

open access: yesRemote Sensing
The Brazilian Atlantic Rainforest presents great diversity of flora and stand structures, making it difficult for traditional forest inventories to collect reliable and recurrent information to classify forest succession stages.

The orbital motion, absolute mass, and high-altitude winds of exoplanet HD209458b

open access: yes, 2010
For extrasolar planets discovered using the radial velocity method, the spectral characterization of the host star leads to a mass-estimate of the star and subsequently of the orbiting planet. In contrast, if also the orbital velocity of the planet would

Benchmarking performance of annual burn probability modeling against subsequent wildfire activity in California

open access: yesScientific Reports
Wildfire simulation is deployed extensively to support risk management, and in the US has driven billions in federal investment. Foundational to strategic risk analysis is spatial information on the likelihood of burning in a fire year, typically ...

A new climate for human nature? Navigating social theory through postnature, the anthropocene and posthumanism [PDF]

open access: yesFilozofija i Društvo
By examining debates on the Anthropocene era ignited by new materialist and posthumanist scholarship, this paper aims to discern how these perspectives can reframe the human-nature nexus.

Catching a planet: A tidal capture origin for the exomoon candidate Kepler 1625b I [PDF]

open access: yes, 2018
The (yet-to-be confirmed) discovery of a Neptune-sized moon around the ~3.2 Jupiter-mass planet in Kepler 1625 puts interesting constraints on the formation of the system.
